2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Third-party content exposure detected (high risk: 0.70). The SKILL.md explicitly instructs the agent to fork and interact with mainnet via third‑party RPC endpoints (e.g., vm.createSelectFork("https://eth-mainnet.alchemyapi.io/v2/...") and Hardhat forking using process.env.MAINNET_RPC_URL), which pulls public blockchain state from external providers that the agent reads and acts on during tests, so untrusted third‑party content can influence tool use and behavior.
The skill is specifically designed for direct financial operations, giving the agent the ability to move money or execute financial transactions — such as payment processing, cryptocurrency operations, banking integrations, or market order execution.
Direct money access detected (high risk: 1.00). The skill is explicitly about interacting with blockchain assets and includes concrete code that sends transactions and manipulates wallets: Hardhat network config uses an ACCOUNT PRIVATE_KEY, tests call token.transfer, impersonate accounts and transfer tokens, vm.deal (fund addresses), and a Mainnet-fork test references Uniswap swaps and interacting with ERC‑20 contracts. These are specific crypto/blockchain operations (wallets, transfers, swaps, signing) rather than generic testing tooling, and therefore enable direct financial execution.
